Warhammer 40,000: Mechanicus - Heretek is a turn-based strategy expansion that continues the tactical campaign of the original game. Players command Tech-Priests of the Adeptus Mechanicus in missions against Necron forces while dealing with internal threats from within their own ranks.
Gameplay
The core loop centers on turn-based combat where each Tech-Priest uses a range of abilities, weapons, and augments to overcome enemies on grid-based maps. Positioning, ability timing, and resource management determine success in each encounter. The expansion introduces the Xenarite discipline, which focuses on xenotech tools that were previously forbidden, opening new options for damage output and support effects during fights.
Customization extends to appearance options for Tech-Priests alongside the new discipline. Players unlock and equip xeno-altered weapons that create different tactical approaches, such as enhanced close-range strikes or area effects. Two additional unit types join the roster: Sicarian Infiltrators for stealth-based ambushes and Ruststalkers equipped with transonic blades for rapid melee advances through enemy lines.
Combat now includes heretek Tech-Priests as opponents who deploy similar but corrupted abilities. These encounters mix with standard Necron threats, requiring adjustments to target priority and formation tactics inside the confined spaces of an Ark Mechanicus vessel.
Game Modes
The experience remains single-player focused, with all content integrated into the main campaign structure. Five additional missions take place aboard the Ark Mechanicus and feature a narrative delivery system where player decisions directly shape the objectives and enemy compositions for that specific battle.
These missions operate separately from the Necron awakening progression timer found in the base campaign. This separation allows more deliberate pacing without the pressure of escalating threats from awakening forces. No separate multiplayer or skirmish modes exist; progression stays tied to the story campaign and its branching choices.
Narrative and Setting
The story explores unrest among the Adeptus Mechanicus during their operations at Silva Tenebris. New narrative events reveal the causes of civil conflict and the motivations of the heretek faction that has turned away from the Omnissiah. Players manage simultaneous pressures from external Necron forces and internal betrayal while advancing the overall campaign.
The setting shift to interior ship environments changes line-of-sight and movement considerations compared to planetary tomb maps. Narrative choices in the new missions influence immediate battle conditions and contribute to the larger plot resolution.
Is It Worth Playing?
Heretek adds five missions, a new discipline, two unit types, and specialized weapons to the existing turn-based tactics framework. Reviews of the expansion itself rate it mixed, with positive notes on the fresh units and weapons alongside criticism of the added story pacing. The base game maintains very positive overall reception for its combat depth and customization.
This expansion suits players already familiar with the original Mechanicus campaign who want more missions and options within the same system. Those seeking standalone experiences or frequent updates will find limited ongoing support, as the title released in 2019 with no further seasons or major patches confirmed.
Consider the content if the tactical decision-making and Warhammer 40,000 faction themes appeal; the new elements integrate directly into existing save files and extend playtime without altering core mechanics.
